I disagree. Have you seen Polanski's "The Pianist"?
The scene were the old man in the wheelchair is tossed out of the window -- that is the banality of evil in one brilliant harrowing image.
Banality implies obscene carelessness, misplaced indifference. Evil is just that.
As far as I'm concerned, Hitler was never the center of nazi-evil - the evil was manifested by the sausage slobbering, beer gulping subcommanders, whose only quality was being banal enough to go through with the filthy details of industrial war.
If there hadn't been so many blubbering miscreants, Hitler could never have accomplished anything of the sort.
